It may shock you that I disagree about Wonder Woman.
WW performs feats that leave people in awe or
wonder.
Wonder Man is simply the lesser known of the two. His anatomy is infused with ionic energy. It is a wonder than he even exists. He has died before and his resurrection is a wonder in itself. He has a string of abilities that are pretty darn wonderous. It is pretty basic and not catchy but simply put, he is Wonder Man.
Slightly off-topic but I wonder (pun intended) if they will spark any romantic relationships for Simon now that the Scarlet Witch is "off the market."
Ms. Marvel and he shared a thing once but Carol is now Captain Marvel. Would that even work? And how would they possibly match-make them if it did?
